To all 07min if may concern:

Be it.- known that I. Misurrx B. Seusxox, a citizen of the l`nited States. residing nt. Meriden, county of Xew Haven, State o1- 5 Connecticut, linx-e invented certain new and 4'useful Improvements` in Casters, of which the following is e. fnli. clear, und exact. description.

f )ly invention relates to certain new :uid useful improvements in casters in which the -parts'are mnde of metal n nd nre so const rueted :1s to iormit the caster propr-r to he. reedily attached or detached from the ekerfso as' to permit the caster wheel to .miete ou its own axis and :it the sume time rotaie in the socket u's the furniture is moved to :and fro in different directions.

The object of the invention is to produce n simple, inexpensive and etl'ecti``e device in which the homingT of the socket within the furniture leg is such as to afford an effective support for the caster, and in which the caster is so associated with the socket that it may he' readily hunched or detached at will7 the weight of the furniture., when :he perte are, assembled, being; carried direcijr on the upper end of the caster pintle rather than on the lower end tl1ereof,nsin tho ordinary eonstruction.

In the drawings, Figure l is n seeiion of the lower end of the furniture leg, with my improved caster socket und easter in place. the' socket und easter being shown in suie eleva.- tion. Fig. 2 is u vertical section of the easter socket 'detached and illustrating the position of the caster in side elevation. Fig. 3 is a plnn view of the socket. Fig. fi is a View of the under side thereof. Fig. 5 is a vertical section thereof. Fig. 6 is n Side vif-v: or" the 40 center guide and caster retainer, deaehed.

A is the exister Wheei. B is e. cket. of the usual form. pivote-.ily supporting said wheel.

. D is the pintle or spindle projeezing from the bracket B.

The. socket is preferably formed o1' three separate pieces. One of these. pie-es I will term the. washer, another me "frame and still another the. "center guide or caster retninerf. E represents the sain esher, the sumo surrounding the lower n-lt of the pintle l). The fr-nine" is preferiterormed of :1 .strip of metal shaped h1.' suim'oi. dies or ns at F2. The sides F F' are semi-circular or curved, so as to present. a hrend convex bearing surface of substantial length and corresponding: to the here of the. furniture leg.; into which the socket is to be mshed. The. center guidi-.end pintle retnlner" is indicated utll, und is formed of e. strip of metal doubled :it its. upper end, ns liestseen in Fig. ti, the sides heir-1;;semiirculnr or curved and of un internal diameter hutslirhtly greater than the diameter of the pint-le The grt, F of the fn-une" hns u central presser mp portion F3 which receives und centers` the upper end of the center guide nn'd pintie retainer lI. The. lower end of the pnrt- H .ney be suitably secure- 1 to the washer E,`3s by s. ilnnge. H. The lower ends of the Side meinhers F F may be formed integrally with the washer E, or secured thereto in any desired manner, n s by tun s 1*".

The center gui( e or pintle ret-einer may 4have indentut-nms, as indicated at Hz H, 'irofernhly nt the edges of the side seams 'orrned hy folding the metal, the purpose ofV nid indentutions being to form inward roeet-ions or nibs which are. to frietionnlljT oek he pintie, l) in place, n recess being formed pi seid pintle to register with the indentajions H2 when the parts are nssem'oled. ni priictice the upper extremity of the pintlewill" tal-ke n hearing in the u er end of the retniner Il sind the loud wilijhe carried thereon. Lateral displncement'will he. prevented by the engegerm-.nt of the pintle with the centering member H et its upper and lower ends.

As shown in Fig. 4, one setof the openin s through which the rangs F project, are su eiently wide to permit. une sido (F') of the socket to yield sullieiently to enable the socket 'to he. pushed into the. opening in the lower end of the furniture leg, so that bv sn outward expansive action the accidente detnchinent of the socket itself will be prevented. The semi-circuler or convex shpe ,of the side members Eel'erds e. oroad surffice hearing between the caster socket and the. inner well of the furniture lee, so that an effective support will be affords Whereas the side members F F are shown as'comrwatively narrow, the width of said mene' v iii-rs muy be increused to any extent desired wit-hom; depart-ing from the spirit or sco e of my invention. These side memhers F are punches, so :is to dnuhie :he nmterif-.l to form 55 two sides F F', connected ni, their upper ends of such din-meter as to fit in the bore int 11o losv which it is desired to insert one of these casters, and thisdiameter may be varied at will to suit varying conditions.

Bythe present construction the centering andretaining device H furnishes at ence a guide and detachable retainer for the easter i without regard to the diameter of the socket.,

as determined by the width of or space'between the side members F F.

By reason of the construction of the pin'tle. guide H asolid bearing is provided at the inner end thereof to furnish a durable and effeetive bear-inir to sustain the weight of the furniture on the Lipper end of the pintle. By forming the locking` nibs ll2 adjacent to the seams in the sides of the pintle guide, sullicient elasticity is provided to permit the bulbl .ous end of the pintle to be pushed into place` from the furniture leg under similar conditions. lVhen the parts are assembled, the lower end of the. legr G rests u on the washer E around the semi-circular si( e pieces FF.

What I claim is:

1. In a caster socket, a washer-like base, a frame including two side members, one of which is laterallyY yielding, said side members being united at the top, a central guide and pintle retainer between said washer and the part connecting the upper ends of said side members and a pintle bearing at the upper end of said central guide arranged to take the upward thrust of a iintle.,

2. In a caster soci frame including two side members, one of which is laterally yielding, said side members being united at the top, a central guide and pintle retainer between .said washer and the part connecting the upper ends of said side members, and a recess in the said connecting part receiving the upper end of said centering device.

3. In a caste-r socket, a washer-like base, a spring frame includingr two side members, a connection for thcupper ends of said side iet, a washer-like base.

-tle guide being' held from lateral displacement partly by said washer and partly by a bearing in the recess in the upper end oisaid frame. ,Y

4. In acastcr socket, accntral pintle guide and retainer, a washer at the lower end t 1ereof, a spring frame carried by said washer overstanding said pintle guide and comprising a yieiding frame having two side members one of which is laterally yielding and a bearing at the upper end of' said pintle guide ends ofvsaid side. inemf arranged to take the upwardthrustof a pintle. p

5. A three-part easter socket comprising a washer at the ower end thereof, a frame, and

`a central pintle guide,said pintle guide being slitted through along opposite sides and having a solid top to form an overstanding bearing for the upper end of the caster pintle to talle theupward thrust thereof.

6. A three-part caster socket comprising a.

washer at the lower end, a frame and a central pintle guide mounted en said washer,"

said pintle guide being slitted through along opposite sides and having a solid top to form a bearing for the upper end of the caster pintle, the side of said guide adjacentone of said slits being 'pressed in to form a pintle lockii. gsl1oulder.

7. A tlireeart castensocliet Vcomprising a washer at the lower end, a frame and a central pintle guide mounted on said washer, said pimle guide being sliited through along op- )ositc sides and having a solid top to form a )caring for the upper end of the caster pintle, the opposite sides of'said pint-le guide adjacent to said slits being pressed in to form a plurality of pintle retainers.

S. ln a caster socket, a pintle guide, means for detachably holding the pintlc therein, a frame external of said pintle-guide at the sides ti'iereol` for detacliabl holding said pintle guide in the furniture eg, and means for receiving and supporting the lower cud of the furniture leg on said societ and a connection between said leg sides of the frame.
